Sainsbury’s is launching a range of 120 new and revamped desserts this month – with some featuring foodie faves, including ancient grain quinoa and citrus fruit yuzu.

The retailer said it had invested in the quality of ingredients used in both the By Sainsbury’s and Taste the Difference products, with all the desserts made using British cream and free-range eggs.

Other improvements, said Sainsbury’s, include a new recipe for its Taste the Difference pastry to boost the crispness and give a more buttery taste. The retailer has also introduced a new custard in its trifles offering a “more creamy texture and flavour”.

The line-up comprises single, twin-pack and sharing options, and includes:

By Sainsbury’s Banoffee Pie (£3.50). Digestive biscuit crumb base, topped with a banana and toffee sauce and fresh cream, finished with milk chocolate shavings and cocoa powder. Sainsbury’s said the base is crispier than ever, and that the pie offers an increased banoffee layer.

News of the launch comes as latest Nielsen data shows Sainsbury’s overall sales fell 0.6% year on year in the 12 weeks to 8 October 2016, with its market share dropping 0.3 points to 15.2%.
